' STEAM COOKING APPARATUS.

SPECIFICATION forming ,part of Letters Patent No. 268,732, dated December 5, 1882.

l Application led April 26, 1882. (No model.)

To all whom it may concern: v y

Be it known that I, WILLIAM C. SALMON, a

citizen of the United States, residing in Cincompartments, so arranged that one or all may be used independent ot' the others, and into which the steamis admitted for cooking. I

The novelty of my invention consists in the construction of .combinations ot' the parts, as will be herewith set forth and specitcally claimed.

Figure l otthe accompanying drawings represents a sectional front view ot the cooking device, showing four compartments for cooki'ng. Fig. 2 is a sectional side view ot' my cooking device, showing theV handles tothe doors or drawers and the locks `or latches for the same. Fig.3 represen ts the bottom of thelower compartment, showing the steam tubes `and valves or dampers; Fig.4, side view of two of the steam tlues and valves. Fig. 5 shows a section of the tube for carrying oft the steam from the compartments and draining them. Fig. 6 shows inclined bracket and catch for fastening the door of the compartment or the drawer containing the material to be cooked in the chamber.

The lower chamber or compartment, A, is provided with a funnel-shaped opening, B, on its side for pouring water in, and a cock, D, for drawing it ott. Above this steam-,chamber are arranged. in succession any convenient l lits snugly the upper end of the section ot' theV number of compartments, (the drawings showing four, E F G H,) and to each compartment independent tubes .e fg h convey the steam from the chamber A. The bottom of each compartment isprovided with anges C, which tit close within the top ofthe compartment below, making a tightjoint or connection. They are also provided with anges or a downward eX- tension ofthe steam-section of the tubes, which pass through them, as shown at I I, into which steam-tube below. By this means any one ot the compartments may be lifted oft', and the one above it will titdown into its place; and, if

jdesirable, all but one may be removed, or any each compartment, justas the steam-tubes are,

as shown at kit. This pipe has an openinginto each compartment at'L L L, through which the surplus steam and vapors arising from the cooking vegetables or meat may pass out, and are 'conveyed to the top, where the pipe descends into a cup of water, M, on the top of the cookingdevice. The steam, passingup through this pipe K K, passes down into the vessel M and escapes through the water contained in it, and in passing through the water in the vessel M the odors are absorbed by the water and the steam and vapors escape into the air odorless. With a moderate quantity ot'water in the vessel M the fresh steam from the boiler, entering all the compartments in use, forces the heated vapors and the steam already in the compart' ments and in the pipe K up through the pipe `K into the water in the vessel'M, through which it escapes in the air. Where it is desired to drain 'the compartments of Water produced by the condensed steam, an opening into the pipe K is made at the bottom ot' each compartment, as shown at n, Fig. 5. The pipe K is provided at its lower end with a cock, O. The opening a may, it' desirable, be used both for the escape ot' the steam and to drain the compartment, thusdispensiug with the upper opening, L. Each compartment is provided with projections P P on its bottom, upon which rest the drawers or vessels containing the material to be cooked, thus permitting the steam to pass beneath and all around the vessel. The compartments may be provided with doorson the sides for introducing a vessel containing the food; or, as shown in the drawings, this door may form part ot a drawer, used as a vessel to y contain the food, as shown at .R R R, with handles S S S, and which slides into the compartment, and is there firmly secured by the latchV IOO .dotted lines in Fig. 2.

T, operated 4from the outside by the handle t. This latch works on an inclined bracket, U, so that by turning the latch firmly the drawer or door may be fastened as tightly as desired. Each compartment is provided with handles V VgV, by which it may be lifted or carried, and each drawer or vessel may be provided with a tightlid, which will preventthe steam comingin contact with the material to be cooked, so that bread maybe baked or anything cooked requiring dry heat, andall the juices or essence retained, so that bread baked in this way is richer and sweeter than in an oven. The top vX has a flange around its lower edge, which tits snugly within the top ot the compartment below it. The bottom ot' the lower compartment, which contains the water to be heated, may be made dat, as shown'in Fig. 1, or concave, so as to retain the heat, as shown by the This compartment also serves as a tcakettle, from which hot water may be drawn at any time by the cock D.

The operation is as follows: rlhe boiler A bein g placed over the tire. and steam generated, the valves J J being open, it passes up the tubes efg h, and, following the line indicated by the arrows, enters the various chambers and heats them with great rapidity, thoroughly cooking whatever may bein them. lf the pans or drawers R are covered with al lid, no steam comesin contact with their contents, and bread may be baked or meat roasted and all thejuices preserved. It' any steam is condensed in the chambers, it is drained otl into pipe K through the opening n, Fig. 5. The surplus steam also passes into the pipe through the openingn or L, and is conveyed up and through the water cup M, where it is deprived of all odors.

Having thus fully described my invention, I claim- 1. In a steam cooking device having a series of cooking compartments, arranged one above the other, and the whole series placed above a boiler, the combination, with each of said compartments, ot separate or independent tubes or ilues connecting with the boiler and provided with valves or dampers, whereby steam may be admitted into anyone of the compartments, and whereby steam in any cooking-compartmentis admitted andkeptindependentofall the others, and a waste-pipe for conveying 01T the vapors or surplus steam, substantially in the manner and for the purpose described.

2. In combinationwith the steam cooking device, the pipe K, arranged outside of but so connected with each compartment as to carry ofi' the condensed steam through the cock O and the vaporsthrough the deodorizing-tank M.

3. In a steam cooking device having a series of removable and independent cooking compartments, arranged one above the other and over a boiler, with steam-connections to each ofthe compartments, the combination, withl said cooking-compartments, ot'a sectional pipe,

K, with openings into each compartment pass-V ing up into a water-tank, M, witha water-sealed connection, whereby the odor-laden steam and vapors escaping from the compartments are rmade to pass th rough the water in the tank M before theyare discharged,substantially as and for the purpose specified.

4. In a steam cooking device having separate and independent cooking compartments, each connected with the subjacent boiler, the combination, with the tioor of each cooking compartment. provided with raised tracks or ribs, of removable cooking-vessels, each resting upon the tracks or ribs of its compartment, whereby the steam entirely surrounds the cooking vessels, substantially in the manner described.
